Description
Technical field
The present invention relates to Casting Equipment technical field, be specially a kind of gravity force casting machine.
Background technology
Gravitational casting refers to that molten metal pours into the process foundry machinery that metal mold cavity obtains foundry goods under terrestrial gravitation effect.Topmost feature in gravitational casting production process, be molten metal is poured into an actor's rendering of an operatic tune obtain foundry goods, die manufacturing cycle is short, and development cost is low, and its mould can adapt to product development stage and constantly adjust needs.
Existing gravity force casting machine vibrational power flow is unreasonable, and guiding accuracy is poor, and collapsible form is easy run-off the straight and deviation under oil cylinder effect, causes watering the foundry goods uniformity cast out bad, easily ruptures; Artificial mold-break operations inconvenience, not only labour intensity is large, inefficiency, and easily damages foundry goods, and percent defective is higher, and quality stability is poor.
Summary of the invention
For the problems referred to above, the invention provides a kind of gravity force casting machine, its structure is simple, and collapsible form not easily tilts and deviation occurs, and guide effect is good, ensure that the end product quality of foundry goods.
Its technical scheme is such: comprise the bearing be fixed on base, it is characterized in that: described base is fixed with oil cylinder of loosing core, the piston rod upper end of described oil cylinder of loosing core is fixed with mold platform, the left and right sides of described bearing upper end is symmetrically arranged with fixed form, the corner of described fixed form is respectively equipped with guide pin bushing, guide pillar is slidably matched through described guide pin bushing and described guide pin bushing, the rear end of described guide pillar is fixedly connected with connecting plate, the front end of described guide pillar is fixedly connected with collapsible form, described fixed form is fixed with die cylinder, the piston rod of described die cylinder stretches out forward and is fixedly connected with described collapsible form, the corner of described bearing is respectively equipped with column, the top of described column is fixed with cope match-plate pattern, described cope match-plate pattern is provided with hoist cylinder directly over corresponding described mold platform, the surrounding of described hoist cylinder is evenly placed with four upper guide bush, upper guide post is slidably matched through described upper guide bush and described upper guide bush, the upper end of described upper guide post is fixedly connected with fixed head, the piston rod of described hoist cylinder protrudes upward and is fixedly connected with described fixed head, the lower end of described upper guide post is fixedly connected with upper collapsible form.
It is further characterized in that: the upper end of described upper guide bush is provided with stiffener, and the corner correspondence of described stiffener is provided with the through hole coordinated with described upper guide post size;
The lower end of described cope match-plate pattern is provided with gag lever post.
After adopting design of the present invention, can according to the multidirectional matched moulds of cast shape, die change is convenient, positioning stablity, collapsible form not easily tilts and deviation occurs, and matched moulds is steadily strong, frictional resistance is little and guiding accuracy is high, and product quality is high, constant product quality, easy to operate, by cylinder ejector workpiece of loosing core, the piston rod of oil cylinder of loosing core is regained voluntarily, and gag lever post plays position-limiting action when hoist cylinder runs, prevent from hoist cylinder from overwalking to clash into, stabilization of equipment performance is good.
Accompanying drawing explanation
Fig. 1 is that master of the present invention looks cross-sectional schematic;
Fig. 2 is diagrammatic side-view cross-sectional schematic diagram of the present invention.
